When your task already has an assignee, and you're calling the claim method, this exception will be thrown.

The task is set to Process initiator and the user is the initiator.
The task doesn't show the form but only the claim button, so that the user have to click claim button and the exception shown in the console.
On the other hand , if a claimed or set assignee task should have the claim button activated. It looks like it is a bug.

Hi,
since this process is designed to start automatically then there is no "process initiator" that's why I don't see any reason to assign the task to the process initiator.
